The military level 7 pants are bulky and not that warm imo. Not sure if that is what has been talked about or not. I do not think they have any wind proofing since that is what the level 5 does. They are very inexpensive thou and I have 3 pairs... For moderate cold and shorter times exposed to that cold the uncomphagre pant is not bad or bulky. I think the best way to go is a good down pant with a light windproof layer over it..like the L-5 military shell pant. But that may not be considered inexpensive as far as the down pants goes, the L-5 can be gotten pretty reasonably depending on the camo option that you choose. I have no issues with my WM down pant and an acu level 5 pant over the (adds wind resistance and protects the down pant).. Packs small and light, pretty warm.
